SYNCHRONOUS PIPELINED
DUAL-PORT STATIC RAM
IDT70V9359/49L
Features:
True Dual-Ported memory cells which allow simultaneous
access of the same memory location
High-speed clock to data access

Flow-Through or Pipelined output mode on either port via
the FT/PIPE pins
Counter enable and reset features
Dual chip enables allow for depth expansion without
additional logic
Functional Block Diagram
Full synchronous operation on both ports
– 3.5ns setup to clock and 0ns hold on all control, data, and
address inputs
– Data input, address, and control registers
– Fast 6.5ns clock to data out in the Pipelined output mode
– Self-timed write allows fast cycle time
– 10ns cycle time, 100MHz operation in Pipelined output mode
Separate upper-byte and lower-byte controls for
multiplexed bus and bus matching compatibility
LVTTL- compatible, single 3.3V (±0.3V) power supply
Industrial temperature range (–40°C to +85°C) is
available for 83 MHz
Available in a 100-pin Thin Quad Flatpack (TQFP) and 100-
pin Fine Pitch Ball Grid Array (fpBGA) packages.

NOTES:
1. "H" = VIH, "L" = VIL, "X" = Don't Care.
2. CE0, LB, UB, and OE = VIL; CE1 and R/W = VIH.
3. Outputs configured in Flow-Through Output mode: if outputs are in Pipelined mode the data out will be delayed by one cycle.
4. ADS and CNTRST are independent of all other signals including CE0, CE1, UB and LB.
5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other signals including CE0, CE1, UB and LB.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed VDD +0.3V for more than 25% of the cycle time or 10ns
maximum, and is limited to < 20mA for the period of VTERM > VDD + 0.3V.

from 0V to 3V or from 3V to 0V.
3. COUT also references CI/O.
